Coprolites

Life on Earth has gone through a lot, and the plants and animals we see today are just a snapshot of all the lifeforms that have ever inhabited this planet. Many animals may be long gone but we know that they did exist because of the clues they have left behind – most obviously their bones, which you can find reconstructed in museums throughout the world. Knowing for certain how these animals lived is almost impossible because we cannot observe them directly. However there is a small corner of palaeontology research that can help to put some flesh on those bones: coprolites.
